This document discusses Snap packages, which are self-contained application bundles that run on Linux distributions without modification. It outlines some challenges of running Snap packages on WSL2, such as Snapd requiring Systemd which is not started by WSL2 by default. It provides steps to install Systemd as the PID1 process to address this. Additional sections cover enabling strict confinement, finding and installing Snap packages, and building your own Snap packages.
